Roadking, I can only speak for the Ford diesel, but it will help you in that the big three are VERY close in mileage figures. If you should run across a few owners telling you that their everyday figures reach 24, uh, well, you can probably spot BS a mile away. We tow the Suites at 62 and get about 9.5 to 11. If we get hilly then it may stay at 9.0 When we are unhooked for a long period we will generally get about 18.5 or so. We just returned form a five day in the UP, normally travelling about 55 or so and got 20.5 for two days straight.
These are real figures, and I think you'll find that all three of the big guys will treat you well.
